10. SANITIZING THE WATER FILTER
Care is taken at the factory to keep your water filter
clean and sanitary. Materials used to make the filter
will not infect or contaminate your water supply, and
will not cause bacteria to form or grow. However,
during shipping, storage, installing and operating,
bacteria could get into the filter. For this reason,
sanitizing as follows is suggestedQ when installing.
=
Press and HOLD button [] ARMHG
on the face plate until RCHG 12:00
begins to flash in the display su
(12:00 AM began to flash
when the transformer was plugged in). The
valve motor begins to run to advance the filter
into the "fill" cycle. Water flows through the
plastic tubing and you will see the potassium
permanganate bottle begin to fill.
a= As the bottle begins to fill with water, press
button [] again. In about 1 minute, you will see
a slow flow of water begin out the valve drain
hose.
b= Wait about 30 seconds, then press button
[] once more. As the valve repositions again, a
fast flow from the filter drain hose begins. This is
the filter "backwash" cycle. Allow the filter to
backwash for several minutes.
C=
=
Press button [] to advance the filter from back-
wash to "fast rinse" cycle. (Water from the drain
hose stops momentarily, then begins again).
After about 2 minutes of fast rinse, PUT THE
BYPASS VALVE(S) IN BYPASS POSITION (SEE
FIG. 10, PAGE 18). Then press button[] once
again to return the filter to "service" position.
DOING THIS RELEASES WATER PRESSURE
IN THE FILTER.
3. Carefully remove the large plastic clip at the filter
valve inlet (see Key No. 62, page 30). Pull the
valve adaptor from the filter inlet.
NOTE:
If bypass valve, Sears Stock No. 42-3437 is installed,
or if plumbing is too rigid to move, also disconnect the
outlet side and move the filter away from plumbing.
(_ Recommended by the Water Quality Association. On some water
supplies, the water filter may need periodic disinfecting. 6
4. Put 1 teaspoon (0.1 ounce) of calcium hypo-
chlorite into the valve inlet as far as possible.
NOTE:
You can buy calcium hypochlorite in tablet or granu-
lar form under trade names such as Perchloron and
HTH.
1Be sure the valve inlet is clean, for a good
sealing surface for the valve adaptor o-ring.
Then, reconnect plumbing to the filter. AFTER
INSTALLING THE LARGE PLASTIC CLIP, PULL
OUTWARD ON THE VALVE ADAPTOR TO BE
SURE IT'S PROPERLY HELD IN PLACE.
=SLOWLY, reposition the bypass valve(s) to
service... FIG. 10, page 18. Open the nearest
_water faucet until you can smell chlorine,
then close.
7. Again, put the bypass valve(s) in bypass posi-
tion. Allow the filter to stand idle for about 45
minutes, while the chlorine sanitizes.
NOTE:
During this time, go to pages 7 and 8 to make the
timersettings. If needed, adjust the feeder valve tube
for potassium permanganate use, page 9. Then,
complete the following steps.
8. After 45 minutes, return the bypass valve(s) to
service position.
=Repeat steps 1,1a and 1b to advance the filter to
backwash. The timer willautomatically advance
the filter through the backwash and fast rinse
cycles, during which the sanitizing bleach is
flushed to the drain.
NOTE:
The backwash and fast rinse cycles take abut 25
minutes. When over, the timer automatically returns
the filter to service (water flow from the drain hose
stops).
10. Open house filtered water faucets and allow to
run until the chlorine odor is gone.
